Low dissolved oxygen concentrations that occur in many bodies of water when nutrients stimulate the growth of algae that subsequently die and are decomposed by oxygen-using bacteria.
Answer:
C. Constant burning of fossil fuels at power plants increases carbon dioxide concentrations in the atmosphere, resulting in faster input of carbon into the atmosphere than the ocean and land can take up.
Explanation:
Nutrient cycling is the process that allows for a continuous and balanced exchange of nutrients between the earth, living beings and the atmosphere. This exchange allows life on earth to be allowed and managed. An imbalance in this exchange can cause very harmful effects that damage the entire system that the earth maintains.
An example of this is the imbalance caused by the excess burning of fossil fuels. That's because the constant burning of fossil fuels in power plants increases concentrations of carbon dioxide in the atmosphere, resulting in a faster entry of carbon into the atmosphere than the ocean and land can absorb.
